I'm still having no luck. I don't understand what the problem is. On the server, the synergy.sgc configuration file looks like this:

Code:
section: screens 
mac: 
switchCorners = none 
switchCornerSize = 0 
quintusxp: 
switchCorners = none 
switchCornerSize = 0 
end 
section: links 
mac: 
quintusxp: 
end 
section: options 
end
No one has any idea? :\
